HI krishna,
I would prepare a csv with key values and upload them in "imported archive".
Now in message mapping create UDF and read the imported archiv:
try {
     InputStream fstream = this.getClass().getClassLoader().getResourceAsStream(fileName);
     DataInputStream in = new DataInputStream(fstream);
     BufferedReader br = new BufferedReader(new InputStreamReader(in));
     String strLine;
     // Read File Line By Line
     while ((strLine = br.readLine()) != null) {
          String ValueLeft = strLine.substring(0, strLine.indexOf(";"));
          if (WertLinks.equals(key)) {
               return (strLine.substring(strLine.indexOf(";")+1, strLine.length()));
          }//if
     }// while
     // Close the input stream
     in.close();
     return "no Value found; check CSV : " + key;
} catch (Exception e) {// Catch exception if any
     return "Error: " + e.getMessage();
The import-paremeters for UDF are:
- key
- fileName
